EXP2-1

基于HHT方法的模拟调频信号的hilbert谱分析(HHT-based method of analog FM signal hilbert spectral analysis)

用脉冲响应不变设计巴特沃斯数字低通滤波器(Designed by the same impulse response digital low-pass filter Butterworth)

说明：  本程序适用于解决优化问题，达到某些问题的优化目标。(This procedure applies to solve the optimization problem, the optimization problem to achieve certain goals.)

该功能能够通过摄像头自动识别目标 并进行准确定位(This feature can automatically identify the target through the camera and accurate positioning)

1．用Matlab产生正弦波,矩形波,以及白噪声信号，并显示各自时域波形图 2．进行FFT变换，显示各自频谱图，其中采样率，频率、数据长度自选 3．做出上述三种信号的均方根图谱,功率图谱,以及对数均方根图谱 4．用IFFT傅立叶反变换恢复信号，并显示恢复的正弦信号时域波形图(1. Produce sine wave, square wave, and the white noise signal with Matlab, and their time-domain waveform display 2. FFT transform, display each spectrum, where the sampling rate, frequency, length optional data 3. RMS to make maps of the three signals, power spectrum, as well as the number of RMS map 4. Restored by inverse Fourier transform IFFT signal and displays the time domain waveforms sinusoidal signal recovery)

说明：  Simulation file in matlab simulink

program about base isolation structure

非线性光纤光学中用来仿真二阶色散、三阶色散以及SPM的程序，对刚开始进行科研的人有很大帮助。(Fiber optics used for simulation of nonlinear second-order dispersion, third-order dispersion and SPM process right to conduct scientific research in the beginning there is a great help.)

说明：  自定义的音频驱动程序支持,该AudioDevice块，船舶与信号处理模块库利用PortAudio沟通与音频硬件(Custom audio driver support, the AudioDevice block, ship and Signal Processing Blockset to communicate with audio hardware using PortAudio)
